Summary of Final Rulemaking
This final rulemaking amends § 302.1(c)(3)(C)(i) and repeals § 302.7. In 1993, the District adopted the emergency affirmative defense provisions in § 302 when it adopted the CAA Title V State Operating Program. On July 21, 2023, the United States Environmental Protection Agency (“EPA”) finalized a rulemaking entitled “Removal of Title V Emergency Affirmative Defense Provisions from State Operating Permit Programs and Federal Operating Permit Program,” which removed all emergency affirmative defense provisions from the CAA Title V program. 88 Fed. Reg. 47029 (July 21, 2023). The Department now removes all emergency affirmative defense provisions to properly implement the CAA as delegated to the District under 40 CFR § 60.4(b)(10). In the cited Federal Register notice, the EPA provided guidance to states on the implementation and revision process to remove CAA Title V emergency affirmative defense provisions from state operating permit programs, and this rulemaking adheres to the EPA’s guidance.
This final rulemaking also amends Chapter 3 to correct a grammatical error in § 302.1(a)(2) and a citation error in § 303.8(c).
